Opis:
The tumor associated antigen RCAS1 (receptor-binding cancer antigen expressed on SiSo cells) expressed with high frequency in various cancer and trophoblast cells, inhibits growth of estrogen receptor-expressing cells and induces apoptosis. Because previous reports demonstrated RCAS1 presence only by non-quantitative immunocytochemistry methods, we decided to use a Western blotting with anti-RCAS1 monoclonal antibodies for estimation of the relative content of the tumor-associated antigen. One hundred tissue samples were assayed (neoplasms, chronic inflammatory diseases, healthy tissues, trophoblasts and placentas at term). RCAS1 was present in all neoplastic, placental and trophoblast tissue samples and its level in malignant samples was statistically significantly higher than in benign neoplasms. The amount of RCAS1 in chronic inflammations was also significantly increased in immune mediated diseases, like allergic nasal polyps and sarcoidosis. The RCAS1 protein was not revealed in healthy mucous membrane and in muscle tissues. The presented results suggest that RCAS1 might play an important role in tumor escape from host immunological surveillance and carry weight in the down regulation of the maternal immune response, thereby maintaining pregnancy.

Opis:
The increasing antibiotic resistance of pathogenic bacteria calls for the development of alternative antimicrobial strategies. Possible approaches include the development of novel, broad-spectrum antibiotics as well as specific targeting of individual bacterial virulence factors. It is impossible to decide currently which strategy will prove more successful in the future since they both promise different advantages, but also introduce diverse problems. Considering both approaches, our laboratory's research focuses on the evaluation of hemocidins, broad-spectrum antibacterial peptides derived from hemoglobin and myoglobin, and staphostatins, specific inhibitors of staphopains - Staphylococcus aureus secreted proteases that are virulence factors regarded as possible targets for therapy. The article summarizes recent advances in both fields of study and presents perspectives for further development and possible applications.
